runtime = no event/command handlers bracoute31-Mar-02 22:41 bracoute 31-Mar-02 22:41  hello, i have created a CListBox object at runtime on my CEditView. Now i want an event to happen when i click on one of its items. The problem is that at runtime there is no event/command handlers by default (i think). Can someone help me to make an event handler out of my runtime created object?

Let's call that CMyListBox. Now, when creating the objetc at run-time, make it a CMyListBox instead and call CMyListBox::Create just as you called CListBox::Create before. If I understood your problem right, this should do.

But now i have to display the font size in a CEditView.... that's where the problem arise.... i cannot convert the int size variable to a CString variable that can be displayed on the CEditView. Can somebody help me convert the int to CString... i used GetEditCtrl.ReplaceSel() to input the font size on the CEditView but the GetEditCtrl.ReplaceSel() only accepts strings... The code is used is listed below [ccode] if(dlg.DoModal() == IDOK) { CString text; text=dlg.GetFaceName(); GetEditCtrl().ReplaceSel(text); int size; size = dlg.GetSize(); GetEditCtrl().ReplaceSel(size); // This is where i get the error message saying cannot convert // int to CString. } [/ccode] 56Kbps of sighs Re: int to CString (look simple but.....) Christian Graus31-Mar-02 22:52 Christian Graus 31-Mar-02 22:52  It is simple. CString s; int i = 10; s.Format("%d", i); // s now == "10" CString::Format takes the same flags as sprintf, because internally it uses a variant of it. I prefer to use ostringstreams, but as you have a CString, CString::Format is the easiest and most obvious way to do it. So it's: CString szSize; szSize.Format("%d", dlg.GetSize()); GetEditCtrl().ReplaceSel(szSize); Christian The tragedy of cyberspace - that so much can travel so far, and yet mean so little.

How to get the correct client rect of the view? Feng Qin31-Mar-02 14:58 Feng Qin 31-Mar-02 14:58  I use the wizard to create the MFC application, choose Explorer style, so ,the app has two view:CLeftView, CRightListView, the following codes: void CRightListView::OnSize(UINT nType, int cx, int cy) { CView::OnSize(nType, cx, cy); GetParent()->GetClientRect(&m_ClientRect); MoveWindow(&m_ClientRect); } the m_ClientRect is the sum of CLeftView and CRightListView, that's not I want to see. How to get only the rect of CRightListView? I'm amumu, and you? Re: How to get the correct client rect of the view?

Re: How to get the correct client rect of the view? Christian Graus31-Mar-02 16:00 Christian Graus 31-Mar-02 16:00  The client rect by definition is relative to the client. To move it, use ClientToScreen from the main window, if that's what you want the rect to be relative to.

Christian Graus1-Apr-02 1:04 Christian Graus 1-Apr-02 1:04  I've got it - get the WindowRect of the control, GetWindowRect as opposed to GetClientRect. Then if that is relative to the entire screen, call ScreenToClient in the window class on that rect to translate it to be relative to the window. yuou want the window rect anyhow if you're going to call movewindow, otherwise you're scrunching the window size down by whatever the non-client area is.

Feng Qin1-Apr-02 14:39 Feng Qin 1-Apr-02 14:39  For example: CLeftView.m_Rect is (0, 0, 100, 100 ), and the rect of CRightView I can get is (0, 0, 50, 100), but the CRightView is on the right side of CLeftView, so, what I get should be( 100+x, 0, 150+x, 100 ), x is the width of splitter.

C++ question Rajveer31-Mar-02 13:34 Rajveer 31-Mar-02 13:34  This is just a C++ question. Does anybody know how to get data from an excel file? I figured out a way to put data to an excel file. I just do this: ofstream outfile("ftest.out"); int a=1, b=2, c=3, d=4; outfile << a << "," << b << "," << c << "," << d; then when I open ftest.out with excel, it recognizes that the comma means to move to the next block. But when I try to get data from an excel file the same way: ifstream infile("ftest.in"); int a, b, c, d; infile >> a >> "," >> b >> "," >> c >> "," >> d; This doesn't work. Does anyone know some other method to get data from an excel file? Re: C++ question Jack Handy31-Mar-02 14:33 Jack Handy 31-Mar-02 14:33  I don't know how to get the data from a normal excel file but I do know why your outfile code worked and your infile code doesn't... Your ftest.out file would be considered a csv file (comma seperated values) and excel supports csv. A normal excel file is not stored in csv format. Sorry I don't really have an answer but at least you know it isn't some little bug in your code. There are a few articles here on codeproject dealing with excel files, maybe you could find an answer there... try here for instance -Jack To an optimist the glass is half full.

Re: C++ question Roger Wright31-Mar-02 14:58 Roger Wright 31-Mar-02 14:58  I haven't tried it, but generally, if you export the Excel file in ASCII or .csv format (whichever it offers you as an option) the result will be a comma-separated text file. You can then read it as char data and parse the fields using the commas as end-of-field indicators. I believe there's a tokenizer function that does this, but I'm far from my MSDN library right now. Check there online for "token" or some such. Re: C++ question Rajveer2-Apr-02 2:34 Rajveer 2-Apr-02 2:34  How do I export the Excel file in ASCII or .csv format? Do you mean that this is an option in the excel program itself, or do you mean that visual C++ has the ability to do this to the file? If its an option in excel itself, could you tell me how to go about exporting the file?
